BARROWI-WHEEL.

SPECIFICATION forming part of Letters ljatent No. 609,303, dated August 16, 1898. I

Application filed April 2,1898. Serial No. 676,226. (No model.)

To aldwhom it may concern.

Be it known that we, ALBIN B. SMITH an JACOB SOHMITT, J r., citizens ofthe United States,residing at Wilkes-Barre, in the county 7 of Luzerne and State of Pennsylvania, have, invented certain new anduseful Improvements in Barrow-Wheels; and we do hereby declare the followingto be a full, clear, and exact descriptionjof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relatesto an improved barrow-wheel; and it consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter described and specifically claimed. a

The objects ofour invention are to pro; duce a barrow-wheel which will be exceed ingly strong and yet cheap of manufacture, the parts being capable of being readily assembled and in case of necessity being separated for the purpose of replacing broken or 7 worn parts.

'In the accompanying drawings, Figure 1 is a perspective view of our improved barrowwheel. Fig. 2 is a vertical cross-section through the wheel, and Fig. 3 is a vertical transverse section through the wheel.

The greatest strain comes on a wheelbarrow when dumping it, andit' frequently oc curs that in such operation aspoke breaks off just outside the hub, for the reason that there is no give or spring to the wheel. Toovercome this defect, we construct the hub of a continuous metal sleeve or tube and securely fit within the same a solid hard-wood plug or filling through which extends a removable gudgeon or shaft. We construct the spokes separate from the hub and extend them through the sleeve and plug or filling and have their inner ends bear upon the gudgeon or shaft. By this construction and arrangement the advantages set forth above are secured, and, in addition, when the gudgeon wears out a new one, can be insertedan important feature, for thereason that it has been found that under ordinary conditions about four gudgeons wear out before 'thewheelbarrow becomes useless. If the gudgeon was made integral with the hub, in addition to not being capable of being removed, it would make the wheel tooheavy and there would be no spring or give to the wheel, as above indicated.

In the accompanying drawings, A repre 'sents the gudgeon B,"the solid filling for the hubgC, thecontinuous outer inclosing tube for the filling; D, the spokes; E, the felly, and F the tire. p The gudgeon or axle A is preferably made from a suitable piece of solid orhollow rod or piping cutinto a suitable length to extend beyond the hub of the wheel and designed to rest in suitable bearings on the barrow. The filling or plug B for the hub consists, preferably, of a cylindrical piece of hard wood of suitable size and length, which isformed with a bore 1) for the reception of the gudgeon or axle A. This filling or-plug is inclosed or surrounded by the continuous piece of metal tubing 0, which extends the entire length of the same. In securing this metal tube or sleeve onto the filling or plug it is preferably I heated so as to slightly expand the same, but

not sufficiently to burn the woodenplug, and in this condition is slipped ontoth'e same, so that when the'sleeve or tube cools off it will be firmly secured on the hard-wood plug or filling. After the sleeve or tube is secured in positionon the" plug the gudgeon oraxle A is driven through the same. ,The wood being very hard and being surrounded by the continuous sleeve or tube 0, there willbe no liability of the plug being split, audit will also be observed that by employing a continuous sleeve or tube instead of a series of spaced rings the plug will not be affected to any extent by the heat of the sun or by water, as would bethe case with a series of spaced rings placed around the plug.

We have found from experience that it is practically impossible to weld spaced rings around the bar and prevent their becoming loose by the effect of the sun and extreme dry weather. After the metal tube or sleeve is in place on the plug two sets of holes, as c c, are drilled into both around the same at proper points from their ends, the holes a being bored at points on ahorizontal line between the holes c, so that when the spokes D are inserted into the holes 0 0 they will be located alternately around the said tube or sleeve. The holes 0 c extend all the way through the tube or plug. It will be observed that by the construction and arrangement thus described the spokes D will pass through both the sleeve 0 and the plug and bear with their inner ends upon the gudgeon or axle A.

The spokes D are formed near their outer ends with shoulders d, which bear upon the under side of the telly E, the extreme reduced ends of the spokes being seated in passages e, formed in the said felly. These passages e are made, preferably, countersunk or flaring, as at 0, so as to receive the battered or riveted ends of the spokes when the same are turned over with any suitable tool. The spokes are bent slightly at their inner and outer ends, as at cl d so that when the ends are in place in the telly and in the hub portion of the wheel the spokes will be given the proper stagger, and thus add to the strength of the Wheel by properly bracing the same. The felly E is made of a single piece of metal bent into the proper shape, and before the tire F is applied the ends 6 e are left slightly apart. This is done to enable the spokes to be readily inserted into the same in building up the wheel. After the spokes have all been placed in position in the hub and felly and secured at their outer ends by riveting, as above described, the tire F is driven onto the felly, which act draws the ends e e of the felly firmly together and causes the spokes to be firmly forced into and held in the hub portion of the wheel. The tire F is made slightly wider than the telly E, and at suitable points around its periphery on both its edges a portion of metal is turned down and over the felly, as at f f, which makes it impossible for the tire to slip laterally or become loose on the felly.

It will be observed that the whole wheel is locked or held together by the tire and that the inner ends of the spokes have a constant bearing upon the gudgeon or axle A. In the event of one of the spokes or the telly breaking it can be replaced by removing the tire and detaching the telly from the upper end of the spokes, whereupon the spokes can be drawn out and new ones substituted, as also could be the felly.

Having now described our invention, what We claim as new, and desire to secure by Letters Patent, is

1. A wheel for a barrow comprising in its construction a stationary removable gudgeon or axle, a hub portion comprising a removable solid continuous hard-wood plug and a single continuous metal inclosing sleeve or tube, the gudgeon passing through the said plug and extending beyond the ends of the same, removable spokes passed into the sleeve and plug, and a tire for the wheel, substantially as described.
